ASTM A131 is a standard covers structural steel plates, shapes and bars intended primarily for use in ship construction. In this standard, Grade A, B, D and E have different applications.

ASTM A131 Grade A
ASTM A131 Grade A shipbuilding steel is mainly used in general commercial vessels, light marine structural constructions and components like plates, frames, and beams. It is suitable for projects requires moderate strength and durability.

ASTM A131 Grade B
ASTM A131 Grade B shipbuilding steel is used in applications which require higher strength and impact resistance, such as naval vessels and heavy marine structural constructions. It is suitable for structural components intended for long-term use in harsh marine environments.

ASTM A131 Grade D
ASTM A131 Grade D shipbuilding steel is commonly used where moderate strength and good welding performance are required. It is suitable for marine structural applications such as offshore platforms and shipbuilding, providing adequate strength and corrosion resistance.

ASTM A131 Grade E
ASTM A131 Grade E shipbuilding steel is also used in marine structural constructions, typically with higher strength and corrosion resistance requirements compared to Grade D. It is suitable for structural components need moderate strength and good welding performance, such as offshore platforms and specific marine engineering projects.
